Product details
Overview
SN65HVD230DR from Texas Instruments is a 3.3-V ISO 11898-2 compliant CAN bus transceiver in SOIC-8 package, featuring high-speed mode (≤1 Mbps), adjustable driver slew rate via RS pin, low-current standby mode (370 μA typical), and ±16 kV HBM ESD protection on CANH/CANL. It interfaces microcontroller CAN controllers with industrial CAN buses.
For engineers reviewing the SN65HVD230DR datasheet, SN65HVD230DR pinout, SN65HVD230DR application, or SN65HVD230DR equivalent, key selection criteria include bus voltage tolerance (–2 V to 7 V common-mode), thermal shutdown (165 °C), VREF output (0.5 × VCC), and RS-controlled operational modes (high-speed, slope control, standby).
Technical Context
The SN65HVD230DR implements a differential CAN physical layer interface with integrated driver and receiver stages, supporting dominant/recessive bus state encoding per ISO 11898-2. Its RS pin enables three functional states: grounded for high-speed switching (tPLH/tPHL ≤85/120 ns), resistor-biased for controlled slew rate (e.g., 10 kΩ → ~15 V/μs), or pulled high for standby (driver off, receiver active).
It features open-circuit fail-safe design, glitch-free hot-plug power sequencing, and robust bus fault tolerance including ±25 V transient immunity and cross-wire/overvoltage protection. The VREF pin provides a stable 1.65 V (at VCC = 3.3 V) reference for external biasing or diagnostics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 3.6 V - ensures compatibility with 3.3-V microcontrollers and avoids level-shifting circuitry. |
| Data Rate | Up to 1 Mbps - supports high-speed CAN FD pre-phase and legacy CAN 2.0B networks without timing violation. |
| Common-Mode Range | –2 V to +7 V - enables reliable operation in electrically noisy industrial environments with ground offsets. |
| Bus ESD Protection | ±16 kV HBM on CANH/CANL - eliminates need for external TVS diodes in most IEC 61000-4-2 Level 4 deployments. |
| Standby Current | 370 μA typical - allows continuous bus monitoring while reducing system power by >99% vs active mode (17 mA). |
| Thermal Shutdown | 165 °C with 10 °C hysteresis - prevents latch-up and permanent damage during sustained bus short-circuit conditions. |
| VREF Output | 0.45×VCC to 0.55×VCC - provides accurate mid-supply reference for comparator-based wake-up detection or bus biasing. |
Pinout & Package
SN65HVD230DR uses an 8-pin SOIC (SOIC-8) package measuring 4.90 mm × 3.91 mm, optimized for automated PCB assembly and thermal dissipation in industrial control modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D (Pin 1) | Driver input (TXD) | CMOS-level logic input from MCU CAN controller; LOW = dominant bus state, HIGH = recessive. |
| GND (Pin 2) | Ground reference | Primary return path for supply and signal currents; must be low-impedance connection to system ground plane. |
| VCC (Pin 3) | 3.3-V supply input | Power source for internal biasing, driver stage, and receiver; requires local 100-nF ceramic decoupling. |
| R (Pin 4) | Receiver output (RXD) | CMOS-level logic output to MCU; LOW = dominant, HIGH = recessive - matches D input polarity for loopback testing. |
| VREF (Pin 5) | Reference voltage output | Stable 1.65 V (at 3.3 V supply) for external circuitry; load current limited to ±50 μA to maintain accuracy. |
| CANL (Pin 6) | Differential bus low line | Terminates to 120 Ω bus end; withstands –2.5 V to +7.5 V absolute voltage; carries inverted half of differential signal. |
| CANH (Pin 7) | Differential bus high line | Terminates to 120 Ω bus end; withstands –2.5 V to +7.5 V absolute voltage; carries non-inverted half of differential signal. |
| RS (Pin 8) | Mode select control | Configures operation: GND = high-speed mode, 10–100 kΩ to GND = slope control, VCC = standby (driver disabled, receiver active). |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898-2 compliance | Guarantees interoperability with all standard CAN nodes (CANopen, DeviceNet, J1939) without protocol translation. |
| Adjustable slew rate | Enables EMI reduction via external RS resistor (10 kΩ → ~15 V/μs; 100 kΩ → ~2 V/μs) without changing firmware or layout. |
| Fail-safe open-circuit behavior | Outputs default to recessive state if CANH or CANL is disconnected, preventing spurious bus arbitration errors. |
| Hot-plug robustness | Glitch-free power-up/down sequencing allows live insertion into powered CAN networks without bus disturbance. |
| High node count support | Input impedance >40 kΩ enables up to 120 nodes on a single 120-Ω terminated bus segment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65HVD231DR | Ultra-low sleep current (40 nA) but disables receiver in sleep mode; identical pinout and SOIC-8 package. | Suitable for battery-powered nodes requiring zero-receive standby; not appropriate where bus monitoring during low-power state is required. | Select SN65HVD231DR only when full receiver disable is acceptable and nanoscale quiescent current is mandatory. |
| TJA1042T/3 | 5-V tolerant; higher VIO range (2.5–5.5 V); no VREF pin; different RS pin behavior (no slope control). | Better suited for mixed-voltage systems or legacy 5-V CAN designs; lacks adjustable slew rate and mid-supply reference. | Choose TJA1042T/3 when interfacing with 5-V MCUs or when slope control is unnecessary and VREF is unused. |
Compared with SN65HVD231DR and TJA1042T/3, the SN65HVD230DR uniquely balances low-power standby (370 μA) with continuous receiver operation and programmable slew rate-making it optimal for industrial nodes needing bus activity awareness without sacrificing EMI control.

FAQ
What is the maximum data rate supported by the SN65HVD230DR?
The SN65HVD230DR supports data rates up to 1 Mbps, as specified in the ISO 11898-2 High-Speed CAN standard. This is validated under recommended operating conditions (3.0 V–3.6 V supply, –40 °C to +85 °C ambient) with propagation delays tPLH ≤85 ns and tPHL ≤120 ns in high-speed mode. The SN65HVD230DR maintains signal integrity at this rate due to controlled driver rise/fall times and low pulse skew (<35 ns).
How does the RS pin function on the SN65HVD230DR?
The RS pin on the SN65HVD230DR configures three distinct operating modes: grounding RS selects high-speed mode (fastest edge rates); connecting RS to GND via 10 kΩ–100 kΩ sets slope control mode (adjustable slew rate); pulling RS high enables standby mode (370 μA, driver disabled, receiver active). This pin is not present on competing transceivers like TJA1042T/3 and provides unique flexibility in EMI optimization and power management for the SN65HVD230DR.
Does the SN65HVD230DR include thermal shutdown protection?
Yes, the SN65HVD230DR includes integrated thermal shutdown protection that activates at 165 °C with 10 °C hysteresis. When junction temperature exceeds this threshold, the driver stage is disabled to prevent damage during sustained bus faults (e.g., CANH-CANL short). Operation resumes automatically once temperature falls below 155 °C. This feature is documented in Section 8.3 of the SN65HVD230DR datasheet and applies across the full operating temperature range.
What is the purpose of the VREF pin on the SN65HVD230DR?
Pin 5 (VREF) on the SN65HVD230DR outputs a precise 0.5 × VCC reference voltage (e.g., 1.65 V at 3.3 V supply), usable for external circuitry such as comparator-based wake-up detection, bus biasing networks, or diagnostic voltage monitoring. It delivers ±50 μA load current while maintaining ±10% accuracy, and is absent on SN65HVD232DR - making it a distinguishing feature of the SN65HVD230DR within its family.
Is the SN65HVD230DR compatible with 5-V microcontrollers?
No, the SN65HVD230DR is designed exclusively for 3.3-V systems: its D and R pins have VIH = 2.0 V and VIL = 0.8 V, matching 3.3-V CMOS logic levels, and VCC must be 3.0–3.6 V. Direct interface with 5-V MCUs requires level-shifting circuitry. For native 5-V compatibility, consider alternatives like TJA1042T/3, but note that those lack the SN65HVD230DR's VREF pin and RS-configurable slew rate.
